Instructions

  1. Preheat oven to 350 degrees.
  2. Lightly grease 2 cookie sheets.
  3. In a food processor, blend sugars, butter, egg whites, and vanilla until light and fluffy, stopping once to scrape down the sides of the work bowl, about 1 minute.
  4. Add the peanut butter and process using on/off pulses until combined, about 20 seconds.
  5. Add flour, salt and baking soda and blend until just combined using 2 to 3 on/off turns; do not over process.
  6. Transfer mixture to a large bowl.
  7. Cut candy bars into 1/2 inch pieces and stir into dough.
  8. Mound dough by 1 1/2 tablespoons onto prepared sheets, spacing 2 inches apart.
  9. Flatten slightly using fingers.
  10. Bake until dry in appearance and centers are slightly soft to touch, about 15 minutes.
  11. Cool on cookie sheets 3 minutes before removing (they will fall apart until the candy hardens up a bit).
  12. Transfer to wire racks to cool completely.
